K9 Advantix II Medium Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs 11-20 lbs. | 1-Mo Supply

5 stars. The fleas showed up. They rented tiny imaginary apartments in my dog's fur. Just a quick drop in a few spots. Now the fleas are packing their bags and moving out. Zero stars from the fleas. Five stars from us.

I’ve been really happy with K9 Advantix II for my medium-sized dog. It’s easy to apply, and I like knowing it’s a product recommended by veterinarians for flea and tick protection. The application is quick and convenient, which makes keeping up with my dog’s routine much easier. So far, it’s been a great choice for us!

So far so good as far as effectiveness goes it’s not a spray. It’s a tiny tube like container. Has a sink, but it’s not too strong. There’s no leakage problems. The value for your money is all right. The appearance is deceiving the boxes. Huge package is tiny. There are seven several different ways you can order them. They come in packages of three 212. I was able to get it within the three hour window so I got it same day.

This worked on fleas. Frontline didn’t work, advantix didn’t work. Advantix II was the only thing that killed the fleas.

I used this on my senior dog and followed the instructions, but it made my dogs skin split open and become a “hot spot” and filled with puss. This required a ~$500 vet visit, including irrigation of the skin, antibiotics, ointment, etc. My poor dog . Horrible product, don’t be deceived by the reviews like I was. The photo attached doesn’t even show the split skin but just the hot spots. Also this is at the top of his back so it’s not like he had been chewing at it or anything because that would not have been possible.
